何承天《鼓吹铙歌》十五首,是南朝文人乐府的开山之作,但其在内容及创作时间的认定方面尚有争议。从文本分析、知人论世等角度入手,可以论定《鼓吹铙歌》十五首的创作主题具有多样性,也并非完成于一时。这一组诗中最早的作品始于隆安四年,为歌颂桓玄、桓温父子而作;最后的作品完成于义熙五年或稍后,为歌颂刘裕而作。这一组作品与何承天晋末政治生涯的变迁息息相关,既是其政治褒贬态度的反映,也是透视其内心复杂情感世界的镜子。 He Chengtian “Advocate Acura” fifteen, is the literary creation of the Southern Song Dynasty Yuefu, but its content and creation time is still controversial. Starting from the perspective of text analysis and knowing the world, we can conclude that the theme of the fifteen pieces of “Acura” is diversified and not completed at the moment. The earliest works in this group of poems began in four years in Longan for the celebration of Huan Xuan and Huan Wen and their father and son. The final work was completed five years after Yi Xi and later for the celebration of Liu Yu. This set of works is closely related to the change of political career in He Chengtian and Jin Dynasty. It is not only a reflection of the attitude of political praise and disgrace, but also a mirror of the complicated emotional world inside.
